【7人CHORUS】インザバックルーム / In The Back Room

this is my first time using Blender and I kid you not it's very different from After Effects. Anyway my first tutorial is not donut that you always see, but making the Backroom and setting up lighting is.

Also somehow, I kinda give up with some 3D scene and instead just render it for the background, can you guess which part is PNG and which one is actually 3D
